BAG-TURNING MACHINE.

Application filed August 14, 1922. Serial No. 581,828.

Be it known that I, JAY TAMASS-Y a citizen of Hungary, and resident of the cit of New York, in the county of New York and State of New York, have invented certain new and useful Improvementsin Bag- Turning Machines, of which the following is a specification.

The present invention relates to improve ments in bag-turning machines, and has for its main objectto provide a device of this type which is entirely automatic in its op-' eration, the only manual work needed being to place the bags upon supporting members or arms, which carry the bags, one after another, within the reach of the turning mechanism.

Another object of the invention is to produce a bag-turning machine, the turning member of which'serves at the same time as a be. filling device.

W1th these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims, without de arting from the spirit or sacrificing any 0 the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accomdrawings, in which Figure 1 is a plan view of a bag-turning machme constructed in accordance with'the present invention; Fig. 2 is a central vertical section taken therethroughfFig. 3 is a front.

elevation of one of the bagsupports, on a larger scale; Fig 4 is a section taken on line H of Flg. 3; ig. 5 is a front elevation of 'a bagsupport witha bag in position thereon,

1g. 6 is a front elevation of a bag support and the turning element disposed in operative relation thereto; and Fig. 7 is a section taken on line 7-'-7 of Fig. 6.

and in the base 10 is journaled a vertically extending shaft 13, to which intermittent movement is imparted from any suitable source of power.- For this purpose, for instance, there is keyed or otherwise attached to the said shaft a sprocket wheel 14, over which runs a chain, not shown, driven b a sprocket wheel on an intermittently moving driving member. To the shaft is fixed, so as to rotate therewith, a drum 15, provided which is so timed in relation to the means for intermittently moving the shaft that the pawl is disenga ed from a notch in the drum immediately before the shaft is given a partial turn, and is permitted to engage the drum, so as to drop into the next notch in the series, at the end of the partial turn given to the shaft. Obviously an suitable means may be provided or this purpose, the one herein described having other been disclosed for the purpose of illustration only.

On the drum is mounted a plurality of ba supports said su ports being equi-dis- 'taii tly spaced and theii' number corresponding, obviousl to the number of notches in the drum. ach bag support comprises a pair of spaced arms 21; and 22', mounted upon a block 23, which is provided with trunnions 24, extending horizontally and being journaled in the drum. The arms 21 and 22 are alike in shape, they being of substantially U-shaped transverse cross-section, the arm 21 being fixed by screws 25, or otherwise, to. the respective block 23, it extending at right angles to the trunnions 2d,

while the arm 22 is pivoted at 26 to the a block 23, the pivot in extending also at right angles to the said trunnions, (Fig. 4). The pair of arms, forming a bag support, are spaced apart, their open sides facing one another, as clearly shown in the several figures of the drawings. On each block is mounted a pin 27 carrying an anti-friction roller 28, which. co-operates with a stationary cam 29 within the drum 15. The ba supports have a tendency to swing aroun their trunnions into substantially horizontal positions, (Fig. 2). The cam 29, in cooperation with the pins on the blocks 23, shifts the bag supports into vertical positions before they arrive in operative relation to the bag turning mechanism.

Each ofthe arms 22 is so designed that it has a tendency to swing toward the respective arm 21 of a bag support, to /facilitate the slipping of a bag over the arms. Each arm 22 has mounted thereon a finger 30, which is adapted to co-operate with a stationary cam 31, the latter being so shaped that the arms 22 are caused to swing around their pivots into parallel relation to the respective arms 21 before a bag support arrives into operative relation to the bag turning mechanism.

The bag turning member comprises a vertically extending tube 32, that is reciprocably mounted upon vertical guide rods 33, the

latter being carried by a frame member 34, which is mounted upon the frame member 12. The transverse cross-section of the tube 32 is such that it fits the arms; of a bag support, when the latter are in their vertical positions and extend in parallel relation to one another. A suitable mechanism 34 is provided for reciprocating the tube 32 in relation to the drum 15, it comprising in the case illustrated in the drawings a lug 35 on thetube 32, said lug being connected by a link 36 with a bar 37. This bar is fixed to a spindle 38, which is oscillatably mounted in a bearing 39, rising from the frame member 12. With the spindle is connected a crank 40, the crank pin 41 of which is engaged by an actuating rod 42, receiving reciprocating motion from any suitable mech-- anism. The last-mentioned mechanism is so timed, that the tube 32 is caused to move on it s downward stroke when a bag support with a bag thereon is brought into alignment with the said tube, the latter moving upwards and 'being disengaged from the said bag support before the drum 15 is set into motion, to bring the next bag support in the series into. alignment with the said tube. 1 a

The operation .of'this machine is asfollows: The drum rotates in the direction of the arrow shown in Fig.1 of the drawings, the bag supports swinging around the trunnions 24 into the positions shown in Fig.2 of the drawings when the pins27 thereof are disengaged from the cam 29, and the arms 22 swinging around their pivot pins 26 toward the respective'arms 21 when the fingers 30 thereof are disengaged from the- .cam 31. When the elements are in the positions mentioned, the operator slips a bag on each bag support, this operation being facilitated by reason of'the fact that the outer ends of the arms are in the positions mentioned nearer one to the other than the width of the mouth of a bag. The bags are then carried one after the other, step by step, into alignment with the tubular turning member 32. While the bag supports, with the bags thereon, move toward the said tubular member, the pivoted arms 22 of the bag supports are swung away from the respective arms 21, thereby distending the mouths of the bags. The supports are also the bag and turning the same, the bag, while being turned and at the end of the turning operation, being disposed between the tube 32'and the inner faces of the arms 21 and 22, as clearl shown in Figs. 6 and 7 of the drawings; .imultaneously with the turning operation a measured quantity of material may be fed through the tubular member 32 into the bag. Obviously the filling of the bag may be accomplished after the turning operation, just as well.

The connection between the spindle 38 and the crank 40 is, preferably, made by a.

spring 43, the latter engaging a lug44 on the crank and a pin 45 on the spindle. The purpose of this arrangement is to permit yielding of the elements, incase a support is not brought into full registry with the tube 32.

What I claim is v 1. A bag turning machine, comprising a bag supporting mechanism including two spaced arms over which a bag may he slipped, and a tubular turnin and filling member'reciprocably mounted 1n relation to and between said arms engaging a positio ed bag and reversing the same while adva cing towardand between said arms.

5. A bag turning machine, comprising a bag supporting mechanism including two spaced arms over which a bag may be slipped, one of said arms being fixed and the other one pivoted, means for causing the free end of the pivoted arm to swing toward said fixed arm to facilitate the positioning of a bag on said arms, means for swinging said pivoted arm away from said fixed arm, thereby distending the bag thereon, and a tubular turning and filling member reciprocably mounted in relation to and between said arms engaging the positioned bag and reversing the same while advancing toward and between said arms.

6. A bag turning machine comprising a conveyer, a plurality of bag supporting frames mounted on said conveyer, each supportin frame comprising two spaced arms over which a bag may be slipped, one of said arms being fixed and the other one pivoted, means for causing the free end of the pivoted arm of each set to swing toward the respective fixed arm to facilitate the positioning of a bag on said arms, means for swinging said pivoted arms away from the respective fixed arms, thereby distending the bags thereon, a tubular filling and turning member, means for causing intermittent mo-.

tion of said conveyer so as to bring said bag supporting members step by step into alignment with said tubular member, and means for causing said tubular member to move into and out of a bag support during each interval of rest of said conveyer.
